This is dated April 1996. The readme's more interesting than the map - it was going to be part of an ambitious 30-level Deathmatch set, with new graphics etc, but of course the designers got bored and drifted apart. The map itself is simplistic and you can run straight to the exit, and it would be too cramped to work in Deathmatch. The effect leading to the exit switch is cheesy but looks nice.
